The Eiffel Tower has closed for the day, victim of nationwide protests over a bill reforming labor laws.

The company that runs France's most famous monument said that with some personnel taking part in Tuesday's strike, there were not enough people to open the Eiffel Tower for the day in conditions sufficient to assure security and public amenities.

Protesters from numerous sectors planned a march in Paris later in the day, as the Senate votes on the controversial labor measure that would make France's 35-hour workweek longer and layoffs easier. The measure must still be reviewed by the lower house.

The bill has led to about a dozen protests in recent months, often tinged by violence.

Five days ago, police allowed only a small march, to ensure security.
